Nearly half of British holidaymakers hate tipping holiday reps and tour guides, according to a survey by the Post Office.
Tour guides and reps topped the list of groups British tourists dislike tipping when abroad. Second were sunbed attendants and third were hotel front desk staff.
The survey also showed that less than a quarter of British holidaymakers know what is customary to tip when they go abroad. Meanwhile, 44% said they tip the same wherever they are.
The Post Office said this showed a lack of awareness that tipping conventions varied around the world.
While the standard tip in the UK is around 10 per cent, restaurants in the US expect 20 to 25 per cent for great service. In contrast, the act of tipping in Japan is considered rude.
Post Office head of travel services Kevin McAdam said: “Tipping can be a minefield. But if you research before you go, it will reduce your chances of causing offence.”
UK holidaymakers appear happy to tip restaurant waiting staff, but 70 per cent begrudge tipping other service staff.
